Your church is too small - at least, your view of what a church is, is too small. Many people see the church as a building, or a bureaucracy, or a Sunday service, but the bible describes the church more as a united body of people, filled with God's Holy Spirit, and given a variety of gifts so that together, we can do amazing things in the world. Believers are given different gifts to do good things within the church and beyond- not everyone has the same gifts, and if they did, the church simply wouldn't operate. The number of volunteers that just make things happen behind the scenes would astound you. No one can say that they can do it all, and no one can say that they aren't needed in the body of Christ (that is, the church).
